Introduction

IMSP1 is a collection of MATLAB routines using the finite element / difference method for the dynamics of predator-prey interactions in 1 and 2 spatial dimension and time with the IMSP first order scheme (part of PRED_PREY_IMSP).

The MATLAB code is mostly self explanatory, with the names of variables and parameters corresponding to the symbols used in the finite element / difference methods described in the papers referenced below. Copies of the MATLAB codes are freely available via the link below.
